Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-3, the positioning device comprises a door opening stop piece 54, a mounting bracket 1 and a circular shaft; the door opening stop piece 54 is arranged on the hinge door through a screw, the bottom of the mounting bracket 1 is fixedly arranged on the ground in the door through a hexagon head bolt, the side of the mounting bracket 1 facing the door opening stop piece 54 is fixedly provided with the mounting plate 2 through a bolt and a nut, the mounting plate 2 is provided with a circular shaft, and the mounting height of the circular shaft is matched with the height of the door opening stop piece 54; the mounting bracket 1 and the mounting plate 2 are provided with through holes so as to be convenient for a round shaft to penetrate, and the round shaft comprises a connecting rod 7 and a pull rod 6 which are fixedly connected; the sleeve 3 is fixedly arranged on the mounting plate 2, the three magnetic rings 5 are sleeved on the pull rod 6, the cover sleeve 4 is sleeved on the magnetic rings 5 and the magnetic rings 5 are fixedly connected with the cover sleeve 4, the cover sleeve 4 is embedded into the sleeve 3, an O-shaped sealing ring 11 is arranged between the cover sleeve 4 and the mounting plate 2, the axial length dimension of the sleeve 3 is smaller than the dimension of the end face of the pull rod 6 from the mounting plate 2 in a free state, and the fragile and vulnerable magnetic rings 5 can be well protected by the aid of the structural design, so that the integral durability of the door opening positioning device is improved; the other end of the connecting rod 7 is sleeved with a compression spring 10, the end part of the connecting rod 7 is provided with a lock nut 8, and an adjusting nut 9 is arranged between the lock nut 8 and the compression spring 10.
When the door opening stop piece 54 collides with the pull rod 6 to form a suction state for door opening positioning, the O-shaped sealing ring 11 is extruded, so that impact force can be reduced to protect the door opening positioning device, and when a certain amplitude of vibration is generated after the door plate is positioned, the compression spring 10 generates damping action to absorb kinetic energy; when the door opening stop piece 54 leaves the pull rod 6 to form a separated state to close the door, the compression spring 10 is compressed, the pulling force of the magnetic ring 5 can be relieved, the door opening positioning device is protected, the O-shaped sealing ring 11 and the compression spring 10 are matched with each other for use, and therefore the durability of the positioning device is improved.
The performance parameters of the compression spring 10 and the O-shaped sealing ring 11 can be adjusted through the actual hinge door quality, the impact force of door opening and closing actions and the pulling force, the mounting bracket 1, the mounting plate 2 and the door opening stop piece 54 can be directly formed by using a steel plate sheet metal part or machining, and in the design of the positioning device, the functional requirement of improving the durability of the door opening positioning device is fully realized under the condition that the door opening positioning is stable and reliable to be ensured. The size of the central hole of the mounting plate 2 is designed and determined based on the step shaft diameter of the cover sleeve 4 and the outer diameter sizes of the compression spring 10 and the O-shaped sealing ring 11, so that the reciprocating telescopic movement of the cover sleeve 4 is smooth and stable when the magnetic steel assembly is in attraction and separation with the door opening stop piece 54, and the function of buffering and absorbing energy is realized.
When the door is opened, after the door opening stop piece 54 enters a magnetic steel suction influence area, the compression spring 10 of the magnetic steel assembly is compressed, so that the pull rod 6 of the magnetic steel assembly extends out, the door is sucked with the door opening stop piece 54 in advance, the door is fixed to a required position under the action of the restoring force of the compression spring 10, the impact force generated by suction collision is reduced by the O-shaped sealing ring 11, and if vibration is generated after the door is positioned, the compression spring 10 can generate a damping effect, so that the door opening positioning device is protected; when the door is closed, the door opening stop piece 54 moves for a certain distance (the hand feeling door opening force is small to large) with the pull rod 6, then the door opening stop piece is separated from the positioning device and the magnetic steel component, and the pulling force generated by the magnetic steel component is relieved by the compression spring 11, so that the door opening positioning device is protected, the impact force and the pulling force received by the positioning device are reduced and relieved by the magnetic steel component, and the fixing reliability and the durability of the door opening positioning device are improved.
When in use, if the magnetic force of the magnetic ring 5 is larger, the elastic force of the compression spring 10 can be properly increased, and the elastic force of the compression spring 10 is selected and recommended to be carried out under the condition that the compression amount of the compression spring 10 does not exceed the maximum compression amount when the door opening stop piece 54 is separated from the pull rod 6. According to the actual hinge door quality and the impact force of the door opening action, selecting an O-shaped sealing ring 11 with proper material size to ensure that the impact of a door opening stop piece 54 on a positioning device can be reduced; the choice of O-ring 11 should also take into account the durability of the ageing and service life of the O-ring itself. The door opening positioning device can be suitable for positioning and buffering functional requirements of hinge doors of cabs of most railway vehicles, and is also suitable for positioning functions of other civil hinge doors.
